Ever wanted to let a friend look through your iTunes music library remotely? Dusty Tunes provides a quick and easy way to index and list your library online. An easy alphabetical listing by Author allows anyone with the proper link to peruse your music collection. Once there, guests can browse, search, and then preview or purchase from iTunes individual songs in your collection.
The owner of the library creates a quick account and then points the site to the file iTunes Music Library.xml (typically located at My documents > My music > Itunes > iTunes Music Library.xml)
The owner can then point friends to the url (http://www.dustytunes.com/user/<owner_username>.php). Mine is located here: http://www.dustytunes.com/user/nmeierpolys.php
